Yes, cataracts are inevitable. They are really a normal part of aging. At the age of 75, I am certain that you have at least mild cataracts already. However, diet, the use of sunglasses, and good luck may allow you to retain good vision without the need for cataract surgery.Thus I wounder is there a good chance I will escape the cataracts? Or is that inevitable, if you live long enough? Does diet make any difference in cataract development? I am 75 now.
Some doctors, I assume, may not call a cataract a cataract until it requires surgical correction. However, any opacification of the lens is a cataract. With a mild cataract, you might well retain 20/20 vision.
However, even a mild cataract will have some effect. You might notice that your night vision is not as good as it used to be. Or that you seem to need more light than you used to when reading. Often times the change is so gradual that people don't realize what they're missing. Here's a good example of the effect a cataract has on your vision:
We are fortunate to live at a time in which cataract surgery is a routine matter and many of my patients see 20/20 the day after cataract surgery.
